Copper Green Glaze of Chinese Traditional Ceramic Glaze

Copper green glaze is one of the indispensable glaze colours in the production of traditional Chinese ceramics. Its main components are black lead, ancient copper and stone. Because the lime glaze containing copper oxide is red in reducing atmosphere and green in oxidizing atmosphere, these green glazes with copper as colorant are called "copper green glaze" or "lead green glaze" because they contain more lead. According to the firing temperature, copper green glaze can be divided into high temperature copper green glaze and low temperature copper green glaze. In Ming and Qing official kilns, copper green glaze is mostly used as low temperature glaze.
